Document Type and Number:
WIPO Patent Application WO/2023/029777
Kind Code:
A1
Abstract:
A refrigerating and freezing device (10), and a refrigeration system (200) therefor. The refrigeration system (200) comprises: a refrigeration assembly (210), comprising a compressor (211), at least one first evaporator (213), and a second evaporator (214) which are used for forming a refrigeration circuit; at least one bypass heating pipe (250), connected to the refrigeration circuit, thermally connected to the first evaporator (213) in one-to-one correspondence, and used for circulating a refrigerant from the compressor (211) to generate heat, so as to heat the first evaporator (213); and at least one bypass guide pipe (260), connected to the refrigeration circuit, having the inlet connected to the outlet of the bypass heating pipe (250) in one-to-one correspondence, and used for guiding the refrigerant flowing through the bypass heating pipe (250) to the second evaporator (214), so that the second evaporator (214) generates cooling capacity. By improving the structure of the refrigeration system (200) for the refrigerating and freezing device (10), the defrosting mode is optimized by means of a simplified structure, and the advantages of high defrosting rate, short defrosting period, and low energy consumption are achieved.
